    using bin = std::bitset<8>;

    void show(bin z, const char* s, int n)
    {
        if (n == 0) std::cout << "┌───────────┬──────────┐\n";
        if (n <= 2) std::cout << "│ " <<s<< " │ " <<z<<" │\n";
        if (n == 2) std::cout << "└───────────┴──────────┘\n";
    }

    int main()
    {
        bin x{"01011010"}; show(x, "x        ", 0);
        bin y{"00111100"}; show(y, "y        ", 1);
        x or_eq y;         show(x, "x or_eq y", 2);
    }

Output:

    ┌───────────┬──────────┐
    │ x         │ 01011010 │
    │ y         │ 00111100 │
    │ x or_eq y │ 01111110 │
    └───────────┴──────────┘
